New method of preparing 2D photonic crystals with big scale based on UV photosensitivity

A new method based on UV photosensitivity is proposed to fabricate big scale two dimensional photonic crystal.The optical transmission properties of designed periodic structure are investigated by numerical analysis.The results show that the 2D photonic crystal fabricated by the new method has a desirable photonic bandgap of TE mode.

Optimized design and experiment of one-dimensional omnidirectional reflector using P-wave angle domain compensated overlapping method

The optimized method of extending the omni-photonic band gap （omni-PBG） was discussed based on analyzing the P-wave reflectivity characteristics in one-dimensional （1D） periodic multilayer film. A visible omnidirectional reflector with hybrid structure was designed using P-wave compensated overlapping in angle domain. The experimental result was in good agreement with the theoretical simulation.
